Featuring extensive connectivity, the Tetrachords can act as a bridge between a modular system and the rest of a studio. The unique, built-for-purpose interface turns a studio into a melodic and harmonic playground. Easily explore anything from unisons and simple melodies to dense note clusters, made-up scales and polytonal mayhem. Inputs and Outputs:- 4 Trigger/Gate inputs- 4 V/oct CV Outputs- 6 CV Mod inputs- Midi In & out via 3.5mm jack (type A and B supported)- Midi in & out via USB C- i2c connectivity to other i2c modules (currently Disting ex, Just Friends and ER- 301 supported) Main Features:- 4 track polyphonic sequencer- Play with common scales or invent completely new ones using the Tetrachords scale concept- Write harmonically rich compositions in real time and modulate them endlessly using the hands on interface or CV- The 4 tracks can be harmonically linked or unlinked.- The 4 tracks are triggered independantly by the 4 trigger/gate inputs or via midi in.- The V/oct CV outputs can be freely assigned to any track, allowing up to 4 voice polyphony on a single track.- Use third party midi to cv modules eg, mutant brains, mmMIDI, umidi to add more CV outputs to tracks.- Midi outputs allow up to 12 notes of polyphony on each track.- Midi In & out can be freely assigned per track.- The 6 Mod inputs can be assigned to modulate virtually any parameter on the module via CV.- Detailed CV modulation tuning allows precise parameter changes.- Included SD card for saving and loading song data and user preferences.- Save up to 8 songs. Each song containing 8 progressions. Each progression containing up to 8 patterns.- Built in tuner, with the ability to save and recall custom oscillator calibrations.- Each track can switch between arp, chord, step sequencer and keyboard modes Dimensions 36 HP 30 mm deep Current Draw 155 mA +12V 30 mA -12V 0 mA 5V
